When you run OfflineMetaRepair, most likely you will run it from your userid or root.  Then we may get some opaque errors like "java.lang.AbstractMethodError: org.apache.hadoop.hbase.ipc.RpcScheduler.getWriteQueueLength()".    If you check in HDFS, you may see that the meta directory is no longer owned by hbase:   $ hdfs dfs -ls /hbase/data/hbase/ Found 2 items drwxr-xr-x - root hbase 0 2017-09-12 13:58 /hbase/data/hbase/meta drwxr-xr-x - hbase hbase 0 2016-06-15 15:02 /hbase/data/hbase/namespace Manually chown -R it and restart HBase fixed it for me.     ...

  Bit late to reply, but if the cluster is secure, try pointing the hbase configuration to the spark driver and executor classpath explicitly using 'spark.executor.extraClassPath' and 'spark.driver.extraClassPath'. Also make sure that the host from where you are running the spark command has the gateway role added.   Example: $ pyspark --jars /opt/cloudera/parcels/CDH/jars/spark-examples-1.6.0-cdh5.7.3-hadoop2.6.0-cdh5.7.3.jar,/opt/cloudera/parcels/CDH/jars/hbase-examples-1.2.0-cdh5.7.3.jar --conf "spark.executor.extraClassPath=/etc/hbase/conf/" --conf "spark.driver.extraClassPath=/etc/hbase/conf/"    ...
